Hi,

I have Lync 2010 issue when people in the office can make  pstn calls via Lync when in the office, or on the VPN, but if connected over the edge server (for instance if using internet from external) it doesn't work but IM still works its just he calling that's not. Basically the call is placed and when it is answered there is ten seconds of silence and then the call drops no sound at all.

- I checked ASA and everything seems fine, nothing been changed.

- Checked Certs and there all fine and active.

i'm not sure what else to check. It was working before but all of a sudden its not.

Snooper log

ms-client-diagnostics: 23; reason="Call failed to establish due to a media connectivity failure when one endpoint is internal and the other is remote";CallerMediaDebug="audio:ICEWarn=0x80120,LocalSite=X.X.X.X:3304,RemoteSite=X.X.X.X:49623,RemoteMR=X.X.X.X:58631,PortRange=1025:65000,RemoteMRTCPPort=58631,LocalLocation=1,RemoteLocation=2,FederationType=0"

please help.

Hi

Could you try it with the -localstore parameter? If not then run the local store config wizard again and choose the ZIP file

thanks

Hi,

I cant find that command, do you know it ? and am I exporting again from the FE server than import to edge server ?

thanks,

Hi

I meant Import-CsConfiguration -FileName C:\edge.zip -LocalStore

thanks

Ok that worked, but I cant restart the services at the moment (during business hrs) I will do it after and I'll let you know.

Thanks,

Hi Mark,

This issue is resolved now.

It was my External AV DNS A record not populating to the outside world.

Now I can make calls from external to internal and vise versa.

I was busy i didn't get back to this post.

thanks.
